Electronics embedded in rigid gas permeable contact lenses

Abstract

An eye-mountable contact lens is provided that includes electronics encapsulated within a rigid, gas-permeable polymeric material. The rigid, gas-permeable polymeric material can be mountable to a corneal surface of an eye or can be disposed on or within a flexible polymeric material that is mountable to the corneal surface of the eye. The rigid, gas-permeable polymeric material can provide structural rigidity and protection to the electronics and/or can allow for long-term dry storage of a chemical sensor of the electronics. The rigid, gas-permeable polymeric materials of the provided eye-mountable devices can be formed by curing a precursor material on or around the electronics and subsequently removing portions of the polymeric material formed by the curing, e.g., to form a rigid, gas-permeable contact lens that at least partially encapsulates the electronics and that has a curved shape that is able to be mounted to a corneal surface of an eye.
